With the aggravation of aging society in China, the number of deaths is increasing every year, and the demand for hospice care is increasing[1]. However, at present, the quality of death is low, and there is a big gap compared with developed countries[2]. Palliative care and hospice care can improve the quality of death. Palliative care is to provide comprehensive and integrated care for patients with incurable diseases, through early identification and assessment, to prevent and alleviate the physical and mental suffering of patients[3]. Hospice care is an important part of palliative care, which provides physical, psychological, social and spiritual care for dying patients through multidisciplinary collaboration to improve the quality of death of patients[4]. In addition to timely assessment and intervention at the early stage of diagnosis of incurable diseases, hospice palliative care in Peking Union Medical College Hospital also pays attention to the quality of life of end-stage patients, aiming at providing physical and mental care for patients throughout their life cycle. General hospitals play a leading role in China's medical system and have comprehensive capabilities in medical treatment, teaching and scientific research. Peking Union Medical College Hospital is the most prestigious large general hospital in China, taking the lead in the field of hospice palliative care[5]. In this study, field investigation was used to summarize the working mode of hospice palliative care in Peking Union Medical College Hospital, in order to provide reference for other general hospitals to carry out hospice palliative care.

A total of nine themes were obtained:work background,development process,team strength,work motivation,professional quality,work content,difficulties and challenges,coping strategies and influence.The"Banyan Tree Model"of hospice palliative care in Peking Union Medical College Hospital was refined。

2.2 Banyan Image Conception and Banyan Model Construction

the image of the banyan tree originated from the author Ba Jin's article"Bird's paradise".A banyan tree has multiplied into a forest in 400 years,providing habitat space for many birds.This study uses the characteristics of banyan tree,"a solitary tree makes a forest"and"a Paradise for birds",to describe the hospice palliative care model of Peking Union Medical College Hospital,emphasizing that its model has been widely disseminated and has a far-reaching impact on the hospice palliative care system in China。
in the"Banyan tree Model",the palliative medical center of Peking Union Medical College Hospital is the first big tree to grow.Based on the appealing Hospital platform and the urgent needs of the society,peace and relaxation took root and sprouted In Peking Union Medical College Hospital.Through teaching,training and referral,the center for palliative Medicine leads the Medical consortium to develop hospice Palliative care.Team strength and work motivation together constitute the internal driving force for upward development,and the good professional quality of workers nourishes the tree like nutrients.the main work of the center has grown into the main branch of the tree.the development of hospice Palliative care is facing many challenges,and the center has perceived the pressure and produced corresponding coping strategies,which further expands the scope of the center's work.the luxuriant leaves symbolize the influence of the center's work,and they gradually expand with the development of the center,sheltering patients and the public(Figure 1)。

2.2.1 General hospital platform is soil

the director of the Center for palliative Medicine has repeatedly said in public that he wants to promote the development of palliative care throughout the country."Peking Union Medical College hospital is the temple of Medical treatment,and the hospice care team of Peking Union Medical College Hospital plays a leading role in theory,education and practice system,so we find the hospice care team of Peking Union Hospital and hope to develop as soon as possible under their leadership"(field notes).the platform of general Hospital is full of opportunities and abundant resources,which is suitable for the construction of hospice palliative care system。

2.2.2 The working background is the root of the tree.

the root of a tree is the solid foundation for the growth of a big tree.the hospital platform provides the fertile soil for the tree to germinate.the social demand for palliative care,the sense of medical mission,and the early cooperation and exchanges have made palliative care take root in China。

2.2.2.1 Strong social demand

Peaceful death has been a simple wish of the people since ancient times,and palliative care can help dying patients realize their wishes and improve the quality of life.Medical staff found the palliative needs of patients in clinical practice,"There are so many end-stage patients who need help,so it is necessary to carry out palliative care"(field notes),thus generating the motivation to learn palliative care。

2.2.2.2 Professional mission

the medical staff of the center and the medical association believe that in addition to saving lives and injuries,helping patients die peacefully is also their mission As medical workers."as a doctor and a hospital administrator,we have the right and responsibility to help everyone die with dignity and peace,which is our goal"(Field Notes)。

2.2.2.3 Cooperation and communication in the early stage

Early mutual understanding laid the foundation for formal cooperation.Among all the cooperative units,some managers and center directors have common learning experience,some have studied the relevant courses of Peking Union Medical College Hospital,and some directors have actively contacted and cooperated,gradually developing support groups,professional training and other forms of cooperation,which has contributed to the formation of the Medical Association of Palliative Medicine Specialties。

2.2.3 Professional quality is the nutrient

the interaction between Medical staff and patients is a key factor in the treatment process,in which the professional quality of workers is stimulated and strengthened in the realization of their own sense of achievement.these professional qualities are like the necessary nutrients For the growth of banyan trees,which contribute to the palliative care work of Peking Union medical College Hospital."for example,Zhao Keshi talked about the eight qualities of a peaceful person.in fact,These qualities are needed in any industry..I think professional qualities can be perceived and strengthened in work"(N1 interview)。

2.2.3.1 Retention Learning

the discipline construction of palliative care In China is still in its infancy,and most of the workers are halfway out,with different disciplinary backgrounds.in the face of complex symptom management,workers should keep learning and supplement clinical experience[8]。 "Tranquilization and palliation are suitable for the second direction of study,and cancer is the most suitable,because patients with end-stage cancer are the most common..When you encounter a situation that you don't understand,consult a specialist,keep learning,at least guide the patient to a professional department to solve the pain..I will learn something for the patient and learn to use new drugs"(field notes)。

2.2.3.2 Sharp Perception

Dying patients often suffer at the psychological and spiritual levels,which cannot Be quantified and require workers to have sensitive perception to detect and evaluate."I think this is the point of the tranquil man,his perception of the suffering of the patient.".Because we go to the patients and the families,we can feel their pain.be sensitive to this,and then do some further excavation and empathy(N1 interview)。

2.2.3.3 No internal friction

In the initial practice of hospice palliative care,workers tend to set higher professional standards,which brings high expectations,and unmet expectations may lead to job burnout.In the face of job burnout,workers will experience a series of loss and reflection processes.These experiences encourage them to reconcile with themselves,reduce their inner consumption,and more clearly realize the meaning and value of their work.At first,we always said whether This case was successful or not.Now we don't worry about it.that's your own definition.you always think That life and death are both peaceful,which is successful.How can there be so many successes and failures?Then you will die if you come.will you not succeed?I accompanied my daughter and accompanied him to do the funeral.this is a success,and I will not be entangled when it is over.(N3 interview)。

2.2.3.4 No judgment

In order to help patients and their families relieve their pain,workers will deeply understand their family and social relations and empathize with each other's feelings.Sometimes this empathy will form a tension with the workers'own values,which will wear down their work energy and enthusiasm.the quality of non-judgment enables workers to identify the differences between others and their own ideas,avoid their own inner conflicts,and maintain a peaceful mind."I think We are doing more and more now,so We don't judge.We used to judge.How can this family be like this?But it's just our own people talking about it.we try not to bring it to the patients.We used to bring it to the patients."(N3 interview)。

2.2.4 Team strength and work motivation are the internal driving force of growth

2.2.4.1 Team Strength

in the palliative medicine center,doctors,nurses and Social workers form a solid iron triangle working model.the external personnel of the center(such as volunteers)are unstable,but the working roles of doctors,nurses and social workers are always stable:the director(doctor)controls the overall situation,formulates development goals,assigns tasks,and follows up the progress of tasks;the head nurse cooperates with the director to carry out the work at the medical,administrative and management levels,organize the nursing team,and is responsible for external training;social workers are mainly responsible for the management and logistics of volunteer organizations.the three cooperate with each other to understand each other's abilities,temperaments and dispositions,and to achieve profound trust.Together,they create an open and warm team atmosphere(Fig.2)."for example,for some special patients,we will set up a group,and then bring in the directors,especially those who set up a group in the early stage,that is,for some difficult or unmanageable symptoms,we communicate directly in the group,which is also a support for the team"(N4 interview)。
图2 缓和医学中心团队构成示意图

2.2.4.2 Working power

Before the establishment of the center,the purpose of the work of the director and the head nurse was very clear,"(1)to help medical staff,improve doctor-patient relationship,and promote mutual trust and understanding between the two sides;"(2)to help hospitals improve service quality,create a brand of humanistic care,and create a warm image of hospitals;(3)it is to help Patients and their families,relieve pain and get peace"(Field Notes).After defining the goal,we can concentrate on promoting the work.patients'recognition of Concord brand and trust in medical staff constitute the internal driving force for workers to persist in development."After knowing the patient's condition,the director connected the video dialed by her husband,and saw that the patient was conscious and even smiling.".Speaking of"I hope to entrust my last days to Concord",the husband bowed his head and endured his grief,and the director's eyes were red when he saw It"(field notes)。

2.2.5 Development process forms the backbone

2.2.5.1 Original intention

Many workers are self-traumatized,some can not bear to see the pain of patients before death,some have deep anxiety and fear of death in their hearts,they find palliative care for different reasons,hoping to alleviate the pain."the average hospitalization rate on our side is about half a year,so I want to redeem myself in the process of confusion..I want to see if someone can survive in addition to this state.".What I mean by survival is that our medical staff can also survive very well,and I want to see how they do it"(N1 interview)。

2.2.5.2 From ward to the whole society

the hospice palliation practice In Peking Union Medical College Hospital began in the oncology ward.in 2012,the director and the head nurse went to Taiwan to study.After returning,they first tried in the oncology ward.the head nurse contacted the volunteer organization of Peking Union Medical College to provide caring companionship for patients on a regular basis.the ward's attempt has achieved remarkable results."in about three years,the atmosphere of our ward has undergone a complete qualitative change,from a negative channel to a positive channel.Although everyone is still very busy,the state of the people working there will change,and they will no longer feel that I want to escape from this place all the time"(N1 interview)。
after accumulating practical experience,the director set up a working group on hospice palliative care and started the consultation work of the whole hospital.During the consultation process,the director will confirm the needs of the treatment team of the original department and the patients and their families,act as a communication bridge between the two sides,help patients make appropriate medical decisions,and teach the treatment team of the original department symptom management experience and communication skills.the work of the center has gradually attracted the attention of all sectors of society.During the investigation,the researcher went through multiple social media shoots.In addition,volunteer organizations have gradually expanded,and volunteers have brought their work experience back to their areas,which has led to the development of local hospice volunteer services."It's also a copy.They(volunteers)take things back After learning,which can drive the development of a region"(S3 interview)。

2.2.6 Work content is branches and trunks

2.2.6.1 Teaching and training

palliative medicine Curriculum:When the Working Group on hospice palliative care was established,it emphasized the"Concord Model,Education First".the director has set up a Palliative Medicine course for medical students to let more medical students know about tranquility and palliation.According to D1,although"front-line doctors sometimes cannot control the treatment decisions of their superior doctors,they can recommend consultation to gradually expand the influence of Hospice Palliative care,so that patients can receive better care and treatment"(collecting data in kind)。
medical consortium training:the training is mainly based on regular ward rounds.in addition,when the Medical consortium unit encounters various emergency problems In the process of care,such as the rapid change of the patient's condition,the treatment team can contact the center personnel at any time to arrange online ward rounds。
training plan:Under the joint promotion of the Center staff and the leaders of the Institute,the center formally recruited the first Training team in June 2023.the trainees are fully involved in the work of the center,learning and experiencing peace and relaxation through practice.Sometimes you really can't say it very clearly in words.but anyway,in their place(Palliative Medicine center),I think the most impressive thing is that they respect patients very much,let them express more and make decisions for themselves,But now we basically do not have this..His way of treating patients can be applied to(our)clinical practice"(N2 interview)."。
Dandelion Plan:in 2022,with the support of the charity fund,Peking Union Medical College Hospital will take the lead in implementing the Dandelion Plan.Every year,one province or region will be selected to provide key assistance,and the staff of the center will personally visit and teach to lead the construction of hospice care in the whole province.Up to now,he has led the hospice care work in three provinces and cities and carried out a series of training seminars。

2.2.6.2

consultation:There are two main purposes of in-hospital Consultation:(1)to help Patients relieve pain and connect resources;(2)Respond to the needs of the original department,act as a bridge to help both doctors and patients communicate,inform the adverse outcome,and talk about the aftermath.patients often say,"I feel better when I see you(the staff of the center)"(field notes)。
outpatient service:In February 2022,The hospice palliative care clinic was officially established,including medical outpatient service and joint outpatient service.Before The opening of each outpatient clinic,the follow-up nurse contacts the patient or family members through the contact information In the registration information to confirm whether the registered person has the need for peace and relaxation.In the joint outpatient clinic,nurses carry out wound care,daily maintenance of venous catheters and other nursing operations for Patients,and carry out health education.the symptom management of terminal patients is more complicated.the center has prepared a series of brochures and small Notes,including medication guidance,grief counseling,body donation process,living will manual,etc.,for family members to read.patients often say,"Your clinic is really good,otherwise we really don't know what to do about it."(Field notes)。
medical consortium referral:There are 7 medical consortium units,which is a multi-level joint system.the center uses this platform to explore the three-level referral system of general hospital,secondary hospital and community home,and to provide multi-dimensional care for patients and their families.in addition to multi-dimensional referral,some secondary hospitals also undertake local hospice care guidance work,"linking a number of community health service centers and pension institutions at the lower level,and establishing a guidance center for the combination of health and medical care for the elderly"(collecting data In kind)。
Anning co-management mode:Peking Union Medical College hospital has not opened an hospice palliative ward for the time being.in 2023,the center jointly opened an Anning co-management bed with other departments in the hospital to provide co-management care for patients with hospice care needs in the hospital.the staff of the center hand over their shifts early every day to ensure the quality of co-management。

2.2.6.3

In the Early stage of hospice palliative care in Peking Union Medical College Hospital,hospice care in China is still in its infancy and needs extensive social publicity.early volunteers also participated in advocacy work in addition to clinical accompaniment.At present,the volunteer organization has a relatively mature organizational structure.in addition to social publicity,it also has the tasks of auxiliary teaching and literature tracking,and each group performs its own duties(Figure 3)。

2.2.7 Difficulties and Challenges are Scars

the construction of hospice care system is full of challenges,which requires the joint development of Medical institutions,the government and all sectors of society.The Center for Palliative Medicine of Peking Union medical College Hospital has also encountered many difficulties in its development.They have sharpened the tree and left hard scars。

2.2.7.1 Workload oversaturation

there are two main reasons for the over-saturation of workload,which is reflected in almost all the workers in the center and the Medical Association:(1)too much energy and time are invested in caring for patients:end-stage patients suffer from multiple levels of pain,and symptom Management requires repeated assessment by medical staff and continuous revision of treatment plans;for psychological,spiritual and other deep-seated pain,the medical association ward has carried out many special projects,such as aromatherapy,music therapy,etc.Behind each service is frequent doctor-patient communication,which often occupies the time of recording documents and administrative management."the director had already seen three patients,and the head nurse finished the first nursing clinic for two hours.".When she left,she kept telling her family members the key points of wound care(field notes).(2)Shortage of staff:According to the Basic Standards and management Standards for hospice care centers(Trial)issued by the National Health Commission in 2017,Hospice care Centers should have at least 50 beds,but There are not enough workers to match them[9]。 In reality,There is even a situation where one team manages two wards.However,there is no targeted performance appraisal for tranquility and relaxation,and it is difficult to attract more medical staff with low salaries.and it depends on the ratio of your beds.there are too many conditions for assessment.the whole hospital knows that the oncology department is the most tired,and Anning is the most tired.But relatively speaking,your mortality rate is also the highest,and the higher your mortality rate,the lower your performance..We hold activities for patients completely free of charge"(N4 interview)."。

2.2.7.2 Lack of financial support

Due to the unclear performance appraisal system,the income of the center and ward is low,and the activities related to tranquility and mitigation are diverse and need sustained and substantial financial support,but at present,the funding they receive can not cover the related expenditure."the center is supported by three charitable funds at the same time..but the director says they can only cover one third of the total expenditure"(Field Notes)。

2.2.7.3 Lack of activity places

some of The units of Peking Union Medical College Hospital and Medical Association have received financial support from the government,and have set up rooms,activity rooms and other places in accordance with national standards.There are also Some hospitals whose ward environment keeps its original appearance and lacks activity Field."in the wards of Union Medical College Hospital,except for the International Department and a few departments,most departments do not have private places such as conversation rooms and tea rooms.When communicating with family members alone,they often stand in the corridor and talk for tens of minutes,and may be interrupted by others.".the center had envisaged applying for an office as a place for talks,but for various reasons it failed to do so"(field Notes)."。

2.2.8 Coping strategies are branching

2.2.8.1 Finding a "companion"

hospice palliative care requires multidisciplinary collaboration to provide comprehensive care for patients.After returning from studying in Taiwan in 2021,The center team sought partners in the hospital who agreed with the concept of hospice and explored the hospice palliative care model together.the director said that her colleagues were enthusiastic about helping her,and her colleagues said to her:I have been in Concord for so many years,and I know how difficult it is to do one thing.At this point,her eyes were red again.(Field Notes)。

2.2.8.2 Collective Appeal Remuneration Package

the center led the Medical Association to call for the improvement of the salary system,hoping that the new system can be introduced and implemented to solve the current shortage of talents and the over-saturation of workload."I would like to appeal for a salary adjustment,or a corresponding charge for hospice care,but the charge should not be too high,and should reflect our value"(N1 interview)。

2.2.8.3 Exploring new ways of working

In order to meet the diverse needs of patients,the working methods of the center have been adjusted to meet the diverse needs of patients.we are constantly groping,and we are changing very fast.In this year,we did not have outpatient service at first,and then we began to go out of the outpatient service…Our way of working has to be constantly adjusted"(N1 interview)。

2.2.9 Influence on growth of leaves

2.2.9.1 Impact on workers themselves

Palliative medicine helps patients and their families to face life and death calmly,and also increases The sense of benefit and achievement of caregivers.the concept of tranquility also permeates their lives and affects their way of doing things."My personality is relatively calm now.I used to be a very irritable person.Although I have some emotions when things happen now,I really digest them very quickly,because I think no matter how big things are,they are not worth life and death"(S1 interview)。

2.2.9.2 Impact on Peking Union Medical College Hospital

After years of consultation,other departments in the hospital learned about palliative care,and the medical staff gradually recognized the concept of palliative care,and many people joined in and tried different treatment options with palliative medicine.For example,in the hemodialysis room,"hemodialysis patients often have skin itching and other discomforts.Originally,doctors and nurses thought that this was normal,but now they began to pay attention to symptom management and began to try medication"(field notes)。

2.2.9.3 Impact on society

Tranquil palliation is to relieve The pain of patients,help their families through grief,and provide them with all-round care,and they are the most direct beneficiaries.the duration of outpatient and consultation in hospice palliative care is 30 to 70 minutes,and long-term communication has established a close doctor-patient relationship.As a family member,I feel too warm.That warmth will directly make you feel less anxious and irritable(S2 interview)。

2.3 Internal mechanism of banyan model

2.3.1 Teaching by example is the core

In the whole banyan model,teaching by words and deeds runs through the whole process,citing real cases for course teaching,making ward rounds for difficult cases of the Medical Association,and directly participating in the peaceful co-management by the training team.the staff of the center not only impart theoretical knowledge,but also impart practical skills through personal demonstration.Hands-on practice enables learners to master rich clinical skills in a short time.Teacher Ning taught me a lot of things,including handing over the shift and so on,and let me do it alone.At that time,I might have stayed up until 11 o'clock in the evening,and I was still doing this..I gradually felt that this was a good way.in fact,consultation and co-management,although we go to every ward every day,I think it is still very substantial,and what we do is very meaningful"(D2 interview)。

2.3.2 Operation mechanism of iron triangle

No matter how the working form of the center changes,the iron triangle relationship among doctors,nurses and social workers is relatively stable and lasting,cooperating with each other and having their own strengths,forming a flexible working circle。
doctor:the leader,leader and pioneer of the team.Based on the characteristics of doctor-patient relationship in China,patients have more trust in doctors than nurses,so doctor-led multidisciplinary teams are more feasible[10]。 in this study,the leader of the Center for Palliative Medicine of Peking Union Medical College Hospital is a doctor,who also focuses on the development prospects of the whole industry in China,so as to formulate the development goals of the team,create a working model in line with the actual social situation,and lead the team to develop and innovate。
Nurse:Collaborator,supporter,and inspector of the team.In hospice care,the role of nursing is no less important than that of medical treatment,playing a cooperative and supportive role,and cooperating with doctors to achieve care goals.Nurses understand the work of doctors,can find clinical and management problems from the perspective of bystanders,and help doctors control the direction of development。
Social worker:observer and caregiver of the team.Social workers are usually able to observe the operation of the whole team from the perspective of bystanders,to detect the working status of team members in time,to provide care and help when other members encounter job burnout and empathy fatigue,to provide a flexible barrier for the team,and to maintain the stability of the team。

2.3.3 Charisma of Leaders

In addition to the platform factor,the center for Palliative Medicine of Peking Union Medical College Hospital can unite so Many resources without the unique personal charm of the leaders,such as selfless belief,practical practice,caring for the team,etc.many people are moved by their beliefs and take the initiative to join the team.Teacher Ning(director of the Center),sometimes if she finds that this person has a little idea to do,she will try to catch such a person,and then slowly develop.I really admire her"(D2 interview)."。

3 Discussion

At present,there is no specialized hospital for palliative care in China.the existing outpatient clinics and wards mainly rely on the medical resources of general hospitals to promote the construction of the local palliative care system through training and guidance to subordinate units[11]。 Through two-way referral to meet the needs of patients in hospital,reduce the burden of patients'families.General hospitals are the foundation of multi-level diagnosis and treatment,and have the most hospice and palliative care resources.They can make full use of inter-hospital joint models such as medical consortium,medical community and telemedicine cooperation to actively provide resources and improve the utilization rate of hospice and palliative care resources[12]。 General hospitals of different sizes can undertake different forms of work and different numbers of patients,so they should explore their own hospice palliative care model and create distinctive brands according to their own actual conditions。
the implementation of hospice palliative care in China is inseparable from the promotion of policies.Since the establishment of three batches of hospice care pilot projects in 2017,the scale of development has been growing[13]。 the proposal of hospice care policy also represents the progress of China's health and welfare undertakings,and is an important issue to meet the needs of our people and promote high-quality development[14]。 policy orientation can lead general hospitals to strengthen their own discipline construction,Plan the Development direction of palliative care related disciplines,and meet the urgent needs of society.In 2022,Beijing issued the Implementation plan for Accelerating the development of hospice care Services In Beijing,which further improved the hospice care service system,provided diversified service needs,and played a leading role for other cities.In addition to Policy guidance,the ability of hospice care team also needs to be strengthened[15]。 Clinical front-line workers should strengthen the concept of learning,actively seek learning opportunities,actively improve their knowledge and skills,and promote and improve each other among teams to meet the personalized needs of people for end-of-life care。
to sum up,hospice palliative care in China is still in its infancy,and the existing care resources are difficult to meet the diverse service needs of end-stage patients.Many medical institutions are exploring localized hospice palliative care models.in this study,field investigation was used to summarize the"Banyan Model"of palliative care based on the platform of Peking Union medical College Hospital,and its internal mechanism was analyzed.the development of hospice palliative care in China reflects the characteristics of institutionalization,and at the same time,front-line workers need to improve their professional level to meet the diverse clinical needs.General hospitals should locate themselves according to their own conditions and actively participate in medical decision-making when carrying out hospice palliative care,so as to promote the continuous improvement and development of hospice palliative care system in China。
